7ea63fbe0b gpu: nvgpu: move init context functionality to gr falcon unit
Moved following functionality from gr to gr falcon common
gr_gk20a_init_ctxsw -> nvgpu_gr_falcon_init_ctxsw
gr_gk20a_init_ctx_state -> nvgpu_gr_falcon_init_ctx_state
gk20a_init_gr_bind_fecs_elpg -> nvgpu_gr_falcon_bind_fecs_elpg

Replaced code in gr_gk20a.c by calling corresponding gr falcon common
calls and moved all relevant code to gr falcon unit.

Moved following gr ops from gr to gr falcon:
int (*init_ctx_state)(struct gk20a *g);

Moved functionality from gr to relevant gr falcon hals:
gr_gk20a_init_ctx_state -> gm20b_gr_falcon_init_ctx_state
gr_gp10b_init_ctx_state -> gp10b_gr_falcon_init_ctx_state

60b1a431c0 gpu: nvgpu: move ctxsw enable/disable and halt_pipe to gr falcon
Following functions are moved from gr_gk20a.c to common gr_falcon.c
gr_gk20a_disable_ctxsw -> nvgpu_gr_falcon_disable_ctxsw
gr_gk20a_enable_ctxsw -> nvgpu_gr_falcon_enable_ctxsw
gr_gk20a_halt_pipe ->  nvgpu_gr_falcon_halt_pipe

Added new gr falcon hal to control ctxsw:
int gm20b_gr_falcon_ctrl_ctxsw(struct gk20a *g, u32 fecs_method,
			u32 data, u32 *ret_val)
Parameters:
fecs_method: will be specified by a generic define provided in gr_falcon.h
header.
data: input data parameter (if any), set it to zero, if method did not
require any data input.
ret_val: pointer to expected output.

Added following ops for gr falcon:
int (*halt_pipe)(struct gk20a *g); -> this is moved from gr
int (*disable_ctxsw)(struct gk20a *g);
int (*enable_ctxsw)(struct gk20a *g);

e0daeeb614 gpu: nvgpu: add missing headers from common gr falcon
common gr falcon has dependency on sec2.h and acr.h headers for
secure ctxsw booting. Code is getting compiled because
gk20a.h included these headers. But for more clarity, added required
headers explicitly in gr_falcon.c.

0f1726ae1f gpu: nvgpu: support for non-secure/secure ctxsw loading
Code for secure/non-secure ctxsw booting spread across gr_gk20a.c
and gr_gm20b.c. With this change this code is move to gr falcon unit.

Ctxsw loading is now supported with 2 supported common functions:
1.Non secure boot:
 int nvgpu_gr_falcon_load_ctxsw_ucode(struct gk20a *g);
2.Secure boot:
int nvgpu_gr_falcon_load_secure_ctxsw_ucode(struct gk20a *g);

Now gr ops function "int (*load_ctxsw_ucode)(struct gk20a *g);" is moved to
gr falcon ops and in chip hals it is set with secure/non-secure booting.

Non-secure booting: nvgpu_gr_falcon_load_ctxsw_ucode support ctxsw loading
in 2 methods: bit-banging uode or booting with bootloader

A. Common and hal functions for non-secure bit-banging ctxsw loading:
Common: static void nvgpu_gr_falcon_load_dmem(struct gk20a *g) ->
Hals: void (*load_gpccs_dmem)(struct gk20a *g,i
			 const u32 *ucode_u32_data, u32 size);
      void (*load_fecs_dmem)(struct gk20a *g,
			const u32 *ucode_u32_data, u32 size);
Common: static void nvgpu_gr_falcon_load_imem(struct gk20a *g) ->
Hals:  void (*load_gpccs_imem)(struct gk20a *g,
			 const u32 *ucode_u32_data, u32 size);
       void (*load_fecs_imem)(struct gk20a *g,
			const u32 *ucode_u32_data, u32 size);
Other basic HALs:
void (*configure_fmodel)(struct gk20a *g); -> configure fmodel for ctxsw loading
void (*start_ucode)(struct gk20a *g);  -> start running ctxcw ucode

B.Common and hal functions for non-secure ctxsw loading with bootloader
First get the ctxsw ucode using: nvgpu_gr_falcon_init_ctxsw_ucode, then
Common: static void nvgpu_gr_falcon_load_with_bootloader(struct gk20a *g)
        void nvgpu_gr_falcon_bind_instblk((struct gk20a *g) ->
Hal: void (*bind_instblk)(struct gk20a *g, struct nvgpu_mem *mem, u64 inst_ptr);

Common: nvgpu_gr_falcon_load_ctxsw_ucode_segments ->
		nvgpu_gr_falcon_load_ctxsw_ucode_header ->
		nvgpu_gr_falcon_load_ctxsw_ucode_boot for both fecs and gpccs ->
Hals: void (*load_ctxsw_ucode_header)(struct gk20a *g, u32 reg_offset,
	u32 boot_signature, u32 addr_code32, u32 addr_data32,
	u32 code_size, u32 data_size);
void (*load_ctxsw_ucode_boot)(struct gk20a *g, u64 reg_offset, u32 boot_entry,
	u32 addr_load32, u32 blocks, u32 dst);
Other basic HAL to get gpccs start offset:
  u32 (*get_gpccs_start_reg_offset)(void);

C.Secure booting is support with gpmu and acr and with following additional
common function in gr falcon.
static void nvgpu_gr_falcon_load_gpccs_with_bootloader(struct gk20a *g) ->
  nvgpu_gr_falcon_bind_instblk and  nvgpu_gr_falcon_load_ctxsw_ucode_segments
Additional basic hals:
void (*start_gpccs)(struct gk20a *g);
void (*start_fecs)(struct gk20a *g);

Following ops from gr is removed, since it is not required to set by chip hals:
void (*falcon_load_ucode)(struct gk20a *g, u64 addr_base,
	struct gk20a_ctxsw_ucode_segments *segments, u32 reg_offset);

Now this is handled by static common function:
static int nvgpu_gr_falcon_copy_ctxsw_ucode_segments( struct gk20a *g,
	struct nvgpu_mem *dst, struct gk20a_ctxsw_ucode_segments *segments,
	u32 *bootimage, u32 *code, u32 *data)

ee06ecfd2e gpu: nvgpu: gr: move init_ctxsw_ucode to common falcon
Move functions related to init_ctxsw_ucode to common
falcon from gr_gk20a.c. Modified code to call this new
function and modified function names in common falcon
to reflect new re-org.
